-tain new and useful Improvement in Corrugated Paper Board Machines, of which the following is a full, clear, and exact description, suchfas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of specification, in which- Figure 1 is a side elevation of a machine of our improved construction. Fig. 2 is diagrammatic sectional view showing the arrangement of the various rollers of our improved machine and also showing the paper passing through said machine. Fig. 3 is a plan view of the machine, parts being broken away.

Our invention relates to a machine particularly adapted for making corrugated packing board composed of two sheets of paper, one plain and one corrugated and commercially known as single faced corrugated paper.

The principal objects of our invention are to provide a simple compact machine which can be operated with little powerA and which will simultaneously heat and corrugate one sheet of paper, to provide means whereby the heated corrugated sheet is maintainedv in a heated condition while a suitable ad-y hesive is applied to thetips of the corr-ugations on one surface, and to provide means whereby the heated corrugated sheet is firmly held while a second plain sheetof 'paper is brought into contact with the corrugated sheet and so held during the passage of the two sheets through the machine.

A. further object of our invention is to provide means whereby the two sheets of paper are held in close contact with each other immediately after the adhesive has been applied to the corrugations of one sheet, and to provide means wherebythe two sheets are thoroughly heated immediately after they are brought together, thus thoroughly drying and setting the adhesive and thereby doing away with auxiliarymeans for eecting the drying and setting operation.

A further Object of our invention is to lprovide for the rapid drying of the adhesive used between the two sheets by thoroughly heating the sheet of plain paper 'and particularly the surface which contacts with the gummed surface of the corrugated paper, before the two sheets are brought together.

To the above purposes our invention consists in certain novel features of construction and arrangement'of partshereinafter t.more fully described and claimed.

Referring .by numerals to the accompanying drawings, 1 1 designates the side frames of the machine which are united by suitable braces and which support the various rollers forming a part`of the machine.

Journaled for rotation in suitable bearings 2 located on top of the side frame 1 are the trunnions of a pair of hollow corrugating rollers 3 and 4, the corrugations on the faces of which extend longitudinally and mesh with one another in order to produce l and -iXed on said extended end is a gear wheel 5. y

Journaled in the frames 1 immediately below the pair of rollers 1, is a shaft 6 on which is fixed a ear wheel '7, which meshes with the gear W eel 5, and located on the end of this shaft 6 is a Wheel or pulley 8 adapted to receive a belt or like driving means.

The trunnions of the rollers 8 and 4 on the front side of the machine are provided with meshing gear Wheels 9, and leading to the interior of the rollers 3 and Ll'through stuifing boxes 10 arranged in the ends of the trunnions on the front side of the machine, are pipes 11, which convey steam, hot'water or the like utilized in heating the corrugating rollers 3 and 4:. 1

Journaled in suitable bearings 12 on the tops of the frames 1 and immediately in front of the roller 4, are the'trunnionsof a large hollow roller 13, the surface of which is provided with corrugations which mesh with the corrugations'of the' roller 4. The

trunnion of this large roller is extended on the front side of the machine, and, fined thereon is a large gear wheel 14, which meshes with the gearwheel 9 on the trunnion of the Aroller 4. A pipe 15 extends through a' suitable stuffing box 16 of this trunnion for the purpose of conveying Huid heating medium to the interior of the large roller 13.

Arranged immediately below the large roller 13 is a roller 17, the trunnions of which 'are journaled for rotation in suitable bearings formed on the frames 1 and located immedlately above said roller 13 is a roller 18, the ends of which are journaled in suitable bearings.

Journaled for rotation in suitable' bearings on the frames 1 immediately to the right of the large roller 13, is a roller 19,

and assing around the rollers 1-7, 18 and 19 and ea'ring upon the surface of thelarge roller 13 is an endless belt 20.A

J ournaled in suitable bearings immediately to the left of the roller 17 'is a small pastev applyingroller21, the surface `of operating in a paste provided with 'a bearings formed on which is .adapted to contact with the points of the corrugations on thel outer surface of the corrugated sheet passing around the large roller 13. The trunnion on the front end of this roller 21 is provided with a pinion 22, which meshes with the gear wheel 14.

A paste feeding roller 23 has its ltrun nions mounted for rotation in suitable bearings on the frames 1,.sa'id feeding roller ot 24 and contacting with the paste app ying roller 21. The trunnion'on the front end of the roller 23 is gear wheel 23, which meshes with the pinion 22.

25 designates a large hollow roller'having a smooth surface and the trunnion'sv of said roller are journaled for rotationy in suitable the frames 1 immediatelybelow and to the right of the roller 17. A pipe 26 passes through a suitab'le stuffing box on thetrunnion at the front end of this `roller 25 for the `purpose of delivering a suitable fluid heating medium to said roller.

Journaled for rotation imsuitable bearings'immediately to the left of the roller 25 is an idle roller 27. p

The s indles or rods carrying the rolls of paper and B for making up the corrugated board are journaled 'in suitable bear'- in s 28 formed lin the lower portion of the si e frames l During the operation of our improved.

machine a belt or the like applied to the pulley 8, drives the shaft (ia-nd by means o'f the meshing gear wheels 7 and 5 the roller 4 is driven. By means of the gear Wheels 9 and 14 therollers 3-and 13 are driven, and thepaste applying roller 21 and the paste feeding roller 23 are drivenby means of the gear wheel 23a and pinion 22, which latter meshes 'with the gear wheel 14.

The rollers 17, 18 and 19 are all idle rollers and merely serve as a support for the endless belt 20, which is driven through friction with the paper passing around 4the roller 13. The' corrugating rollers 3 and 4, the large roller 13 and the roller 25 are heated 'to the proper ldegree by a suitable fluid heating medium, which is delivered to said rollers through the various pipes entering the trunnions of said rollers. The web ofthe roll of paper 4A passes upward vbetween the rollers 3 and 4 and is corrugated thereby, and after passing partially around the roller 4 passes between the rollers 4 and 13. Thus said web of paper is corrugated and at the same time heated, and as said paper remains in contact with the corrugated surfaces of the rollers 4 and 13 the corrugations become in a measure set owing to the pressure of the heated corrugating rollers. Immediately after the paper passes between the rollers 4 and 13 a suitable adhesive is applied' to the tops of the corrugations on the outer surface of the paper ,by means of the roller 21, which receives the adhesive from the surface of the feed roller 23 operating in the paste pot 24, AThe web of the roll of paper B passes upward over the idle roller 27, thence 'around the roller 25, whereby said paper is heated and from thence around the roller 17 and the belt 20 operating thereon, and said web is thus brought into contact with the gummed surface of the corrugated sheetat a point immediately adjacent the point where the adhesive is applied to the corrugated sheet. The two sheets of paper now pass partially around the roller 13, and said sheets are held in closecontact by means of the belt 20, and owing to the heating of both sheets prior to their coming in contact with one another and 13, the adhesive will be very quickly and thoroughly dried by the time the two sheets pass out` of the machine.

It will be noted in our improved machine that one sheet of paper is corrugated between a pair of heated rollers, and consequently, is thoroughly heated before receiving the adhesive. is first heated and then brought into contact with the heated corrugated sheet and the two sheets are held in close contact during their passage around a large heated roller, thus giving the adhesive ample time to become dry and set. During'the time the two sheets of paper are held in contact with one The plain sheet of paper another, vthey are prevented from creeping,

relative to one another, by reason of the pressure of the belt 2O against' the plain sheet andby reason of the engagement of the corrugated sheet in the roller 20.`

lA machine of our improved construction corrugations on thev .pair of rollers for is comparatively simple, is very compact,

and therefore occupies little floor space, can

be operated with little power and produces a strong, smooth rugated board. IVe clai-m:
